Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621080, here are decompositions:

3 + 8621077 = 8621080
29 + 8621051 = 8621080
71 + 8621009 = 8621080
107 + 8620973 = 8621080
131 + 8620949 = 8621080
137 + 8620943 = 8621080
233 + 8620847 = 8621080
239 + 8620841 = 8621080

Showing the first eight; more decompositions exist.
